Javascript 从多个数组对对象进行分组？

我正在将子对象与父对象分组。我有一个简短的工作示例

它工作得很好，我理解在一个数组中嵌套对象的原理。现在我想使用两种不同的作用域数组。 公司（母公司）-工人（子公司）示例：

$scope.parent = [{id: 1, name: "Nike", productOf:"USA"}]
$scope.child = [{ id:1, firstName:"John", lastName:"Doe" },
                { id:2, firstName:"John2", lastName:"Doe2" },
                { id:3, firstName:"John3", lastName:"Doe3" }
]

我真的试着自己做这件事，我读了很多文章，但我没有找到我需要的

有人能给我一个提示做什么，或一篇文章的链接吗？

谢谢大家!

我认为您需要在子范围中使用一个引用父索引，比如

$scope.parent = [{id: 1, name: "Nike", productOf:"USA"},
                 {id: 2, name: "Fila", productOf:"CH"},
                 {id: 3, name: "BLA", productOf:"UK"}]
$scope.child = [{ id:1, firstName:"John", lastName:"Doe", pid:1},
                { id:2, firstName:"John2", lastName:"Doe2", pid:2 },
                { id:3, firstName:"John3", lastName:"Doe3", pid:3 }

无论如何，您必须在workers数组中具有指向公司的映射字段，然后才能在ng repeat中使用

$scope.workers = [
        { id:1, companyId:1, firstName:"John", lastName:"Doe" },
        { id:2, companyId:2, firstName:"John2", lastName:"Doe2" },
        { id:3, companyId:3, firstName:"John3", lastName:"Doe3" },

输出应该是什么？输出应该与Plunker上现在的输出相同。这是一个赋值。我看不到父项和子项之间有任何关系（公共值）。我应该做点什么歐津柏 说。子id指向父id。输出应该是什么？输出应该与Plunker上现在的输出相同。这是一个赋值。我看不到父项和子项之间有任何关系（公共值）。我应该做点什么歐津柏 说。子id指向父id。这正是我需要的！这正是我需要的！

  $scope.parentObj = [
